Answer:

  F.  120°

Step-by-step explanation:

Call the point of intersection of the altitudes X. Then the measure of n° is the sum of the opposite interior angles of triangle XNQ. Those angles are the right angle (90°) at Q and half the 60° vertex angle at N:

  n° = 90° + (1/2)60° = 120° . . . . matches choice F

Which second degree polynomial function has a leading coefficient of –1 and root 4 with multiplicity 2?
Fynjy0 [20]

Answer:

-(x-4)^{2}

or -x^{2}+8x-16

Step-by-step explanation:

Given a second degree polynomial has a root 4 with multiplicity 2

That means, 4 is a repeating root of the polynomial.

Any second degree polynomial has at most 2 real roots.

⇒Both roots of the polynomial are 4.

and its expression can be written as c·(x-4)^{2} where c is a real number

⇒c·(x^{2}-8x+16)

⇒cx^{2}-8cx+16c

Also, the leading coefficient is given as -1

So, c = -1

and the expression becomes (-1)x^{2}-8·(-1)·x+16·(-1)

⇒<u>-x^{2}+8x-16</u>

The liabilities of Cullumber are $99,000. Owner’s capital is $143,000; drawings are $96,000; revenues, $467,000; and expenses, $
omeli [17]

Answer:

Total assets = $312000

Step-by-step explanation:

Initial capital of the company = $143000

Drawings = $96000

Revenue = $467000

Expenses = $301000

Now to find the current capital or equity of the company :

Equity = initial capital + Revenue - Drawings - Expenses

          = 143000 + 467000 - 96000 - 301000

          = $213000

Now, liabilities = $99000

And the total assets of the company is given by :

Total Assets = Liabilities + equity of the company

⇒ Total assets = 99000 + 213000

⇒ Total assets = $312000

Hence, Total assets of the Cullumber company = $312000
